Hydrophobic molecules

The term "Hydrophobic molecules" refers to a broad physicochemical classification of substances that are non-polar and repel water, tending to aggregate in aqueous environments [1]. In a biological context, this category encompasses a vast array of essential molecules, including fatty acids, phospholipids, cholesterol, and lipid-soluble vitamins (A, D, E, and K), which are fundamental to the structure of cell membranes and energy storage [2]. While not a specific therapeutic target itself, the metabolism and transport of hydrophobic molecules are central to the development of various cardiovascular and metabolic diseases [3]. Furthermore, hydrophobicity (or lipophilicity) is a critical parameter in drug design, as it dictates a molecule's ability to cross biological membranes and determines its overall pharmacokinetic profile [4]. Because this entry describes a general chemical property rather than a specific protein, receptor, or enzyme, it does not function as a distinct target for drug discovery.
